. . convert electrical energy into heat. Electric charge flowing down a potential gradient, as it does in a resistor, is the condition identified by Poynting's theorem for energy to leave the electromagnetic field.
The load current will lead the supply voltage by some angle greater than zero degrees, but less than 90 degrees.
become excited and emit light
lead the voltage
A circuit in which elements are connected in series.For example in RLC series circuit resistor,inductor and capacitor are connected in series.
The same as the time constant of a 2.7 microfarad capacitor and a 33 ohm resistor connected in series.
because without using capacitor or resistor in a circuit,it cant be complete.Resistor is used to protect the circuit by giving a certain amount of voltage.Capacitor is used to charge and discharge purpose.
A resistor&capacitor are in series with a variable inductor.When the circuit is connected to 200v,50Hz supply,the maximum current obtained by varying the inductance is 0.314A.The voltage across capacitor,when the current in circuit is maximum is 800v.Choose the values of series circuit elements?
Current I=V0/R as per OHMs law: V=IR Charge on capacitor Q=CV=It

I wanna use resistor , capacitor and amplifier 7173 for switch alarm circuit. How can i choice resistor and capacitor value because i wanna use 24V DC.
need to use BC107 transistor which has three terminals base, collector and emitter........ collector is connected with 6.8k ohm resistor other end of this resistor is connected with 3.7 ohm resistor and it is connected to the base of the transistor which is already connected to a capacitor of 1 micro F and a positive of function generator......and in the output side i.e in the collector and emitter side connect the 1 micro F capacitor and 10 kohm resistor and connect the CRO...... then other to the ground.......
when we replace the resistor with a capacitor ,the current will flow until the capacitor charge when capacitor will fully charged there is no current through the circuit because now capacitor will act like an open circuit. for more info plz E-mailt me at "zaib.zafar@yahoo.com"
fully charged.

R for resistor, C for capacitor. RC circuit is a circuit built with a resistor and a capacitor. This circuit will have a typical pulse response that looks like exponential decaying and a typical resonance frequency.
If there are only a resistor and a capacitor in the circuit, then the phase shift will indeed be between 0 and 90 degrees. When the resistor and capacitor are in series, the phase shift will be negative when the capacitor is connected to a source voltage and the resistor is the load. The phase shift will be positive when the resistor is connected to the source. The lower the values of R and C, the higher the frequency bandwidth.With the resistor and capacitor connected in series and the two parts connected to a current source, the phase shift will be negative. At high frequencies, the output voltages is lower, and the circuit appears as a very low impedance. At low frequencies, the circuit looks more like a resistor. Again, the phase shift will be between 0 and 90 degrees.CommentThe correct term is phase angle, not 'phase shift'. By definition, the phase angle is the angle by which the load current leads or lags the supply voltage. For an RC circuit, the current leads the voltage, so the phase angle is a leading phase angle.
The equation for such circuits is given by: V=R*I +(1/C)*Integration(idt)
A fractor is a circuit component that has both the function of resistor and capacitor.
